1- Claim; (e1. 12-'-;123)

This invention relates to an improved shoe repair last for use in presses utilized in applying cemented soles, andthe primary object ofthe invention is to provide an. arrangement ofthis character inwhich a. plurality of different sole plates is providedfor interchangeable use, and which involves an adjustable arch plate to accommodate shoe arches of'diiferent heights, the said arrangementgbeing provided in a simple and inexpensive form;

Other important objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the appended drawings; wherein for purposes of illustrationI have shown preferred embcdiments of the invention.

In the drawings:

Figure 1 isa. general side elevational view of an arrangement in accordance with the present invention. a

Figure 2 is a top plan view of Figure 1.

Figure 3 is a top plan view of the sole plate jack.

Figure 4 is a fragmentary side elevational view of the sole plate jack.

Figure 5 is a fragmentary longitudinal vertical sectional View taken through the foot of the sole plate jack.

Figure 6 is an enlarged fragmentary transverse sectional view taken through Figure 3 along the line 66.

Figure '7 is a bottom plan view of the sole plate.

Figure 8 is a transverse vertical sectional view taken through Figure '7 alongthe line 8-8.

Figure 9 is a top plan view of a form of sole plate for use in repairing shoes having metatarsal pads.

Referring in detail to the drawings, the numeral 5 generally designates the sole plate jack comprising a substantially U-shape reclining form made of suificiently heavy gauge metal and including the foot 6 which has a substantially horizontal plain surface 1 on its bottom which is indented with a series of longitudinally spaced sockets 8 to selectively receive the studs on the press bed (not shown) of the press with which the device is to be used. The upper arm of the U-shape constituting the sole plate jack constitutes the head 9 which includes a substantially horizontal plain upper surface H), which has the irregular plan shape shown in Figure 3, produced in part by the arrangement of the plane parallel, longitudinally staggered surfaces 1 land l2, formed on the opposite sides of the head 9. The left hand end of the head has an upwardly offset abutment l3 and the right hand end of thehead has an oppositely offset. abutment. H; the top surfaces of whichform portions of: the plane horizontal upper surface HI. Projecting laterally from the side surfaces H and I2 are the outwardly spring pressed ball detents l5 and. I6 which are also longitudinally staggered in location as shownxin Figure 30f. the drawings:

The interchangeable last plates maybe provided in any suitable number according to the variations in shapes and sizes required forthe contemplated repairing operations, each of said plates comprising a sole-shaped flat body llhaving' a substantially horizontal plain under surface 3 to rest upon the top surface ID of the head. 9, the upper side of the flat body being convexed as indicated by the numeral l9 to com form to the curvature of the sole of the shoe to be repaired. The rear portion of the sole plate is tapered and feathered as indicated by the numeral 20.

The sole plates I! have transversely spaced lugs 36 and 31 depending therefrom in longitudinally staggered positions and formed on the inner sides with ball detent receiving sockets 38 into which the ball detents l5 and HS snap to hold the sole plate immovably on the head of the jack 5 and with the lugs adjacent the corresponding abutments l3 and I4.

A horizontal pivot 2| traverses the upper rear lug 2| of the head 9, and the arms of a clevis 22 are disposed on opposite sides of the head 9 and mounted on the pivot 2!. The said clevis is integral with an arch plate 23 which is in the form of a flat bar having a suitable longitudinal curvature in a downward direction to conform generally to the curvature of the arch portion of the soles of shoes to be repaired. The arch plate 23 is relatively wide at its forepart as indicated by numeral 24 in Figure 2 of the drawings commensurate with the width of the feathered part 22 of the sole plate ll, the inner side of the arch plate being reduced curvedly as indicated by the numeral 25, the free end of the arch plate being rounded as indicated by the numeral 25 to conform to the curvature of the portion of the shoe to be repaired. A wire spring arrangement operating between the lug 2| and the arch plate 23 to urge the latter yieldably in a downward direction, has arms 22' bearing downwardly on the arch plate between the arms of the clevis 22, as shown in Figure 2 of the drawings.

An intermediate part of the bottom of the arch plate 23 has secured thereto a pair of depending arrangement in the rear edge of the bight portion of the sole plate jack 5 as shown in Figure 1 of the drawings. 7

The pawl or dog 29 comprises the rearwardly offset body 33 from the front end portion of which depends the arm 34 which terminates in the point 3| winch enters the selected one of the notches 32 and is provided with a flat abutment 35 on its underside to present a relatively large area to rest upon the lower side of the selected notch.

The arch plate 23 and the pawl or dog 29 remain connected with the jack 5 and are subject to adjustment in accordance with the slant of the arch of the shoe to be resoled.

Upward adjustment can be made simply by lifting upwardly on the outer end'of the arch plate, while downward adjustment requires manual withdrawal of the dog 29 from the particular notch 32 with which its terminal 3| may be engaged at the time, and its replacement in a lower notch. V

For use in resoling shoes involving soles having metatarsal supports built therein, the alternative form of sole plate Ha, shown in Figure 7 of the drawings, is utilized, the main distinction being the presence in the rear portion of the sole plate of the relatively large oval opening 39 through which the metatarsal pad can project to allow the remainder of the sole to come flush upon the top surface I 9a of the sole plate lla.

In utilizing the invention, a pair of the devices is employed, and a pair of sole plates I! are selected which conform to the size and shape of the shoes to be repaired, vand the sole plates are installed on the jacks. The arch plate 23 is then adjusted to the proper angulation, and the shoe to be resoled is placed on the device, and the cement sole is then put in place. The device as a whole including the sole is then transferred to the press, of which several types are in use, and the well known operations of pressing the sole in place are performed.

Although there are shown herein preferred embodiments of the invention it is to be understood that it is not desired to limit the application of the invention thereto except as may be required by the scope of the subjoined claim.

Having described the invention, what is claimed as new is:

A last for resoling shoes comprising a jack including a foot for resting on a support and an elongated head, a sole plate for imposing on said head, and coacting devices on said head and plate for detachably securing the plate on the head comprising a. pair of bottom lugs on the plate opposed to opposite sides of said head to straddle the same, and snap action devices on said sides of the head and on said lugs, respectively, for locking the lugs to the head, said devices comprising a pair of lugs on opposite sides of said plate adaptedto straddle said head and having sockets therein, and a pair of spring loaded ball detents mounted in opposite sides of said head for seating in said sockets..
